nfs directory mount hangs after switch from one vpn connection to another one

[bsgcic]

Binary package hint: network-manager

1. Using network manager, connect to VPN site A which has an ubuntu 10.04 LTS server running nfs.

2. Mount a directory to /mnt/siteA from that server on the local client server running ubuntu 10.04 LTS (the 2 servers are almost clones).

3. Unmount /mnt/siteA

4. Using network manager, disconnect VPN site A

5. Using network manager, connect to VPN site B which has an ubuntu 10.04 LTS server running nfs.

6. Try to mount a directory to /mnt/siteB from that server on the local client server running ubuntu 10.04 LTS (again, the 2 servers are almost clones).

7. Mount will hang. Also, just doing a ls /mnt hangs.

Tried restarting many services to no avail.

Only workaround is to reboot the client and then create a fresh VPN connection to site B. Then can mount /mnt/siteB.

This isn't a bug in NetworkManager, but an issue with NFS. In this case the mountpoint is probably not being fully unmounted before you disconnect, or there's something being cached. Reassigning to nfs.

Status changed to 'Confirmed' because the bug affects multiple users.
